Misconceptions That Cost Us
Every day in salons and forums, you hear assertions like “wash every day,” “use the
strongest heat settings,” or “hair grows faster after a cut.” But science and
dermatologists tell another story — one rooted in hair biology, scalp health, and realistic
expectations.
Myth 1: Overwashing = Cleaner, Healthier Hair
The truth is, excessive shampooing strips natural oils (lipids, ceramides) from the scalp
and shaft, causing dryness, frizz, and fragility. Leading trichologists now advocate for
tailored washing frequencies— oily scalps might need more frequent washing, dry or
curly hair much less. Moreover, sulfate-free, gentle cleansers are increasingly
recommended in place of harsh detergents.
Myth 2: “Good Products” Make Heat Safe
Heat tools (flat irons, dryers) can exceed 200 °C, which can denature keratin — the
protein backbone of hair. Even high-end heat protectants don’t completely prevent
damage, though they mitigate it. Stylists often counsel lower temperatures, reduced
exposure, and letting hair air-dry when possible.
Myth 3: Frequent Trimming Encourages Growth
Hair grows from follicles beneath the scalp; trimming only affects the ends. But regular
trims (every 6–8 weeks) help remove split ends and prevent breakage, making hair
appear healthier and thicker over longer periods.
Myth 4: Tight Hairstyles Are Harmless
Constant tension from tight ponytails, braids, or extensions may induce traction
alopecia, a preventable hair loss from stress on hair follicles. Dermatology research
emphasizes alternating hairstyles, using soft elastics, and giving hair breaks.
What the Experts Say
In industry media like American Salon (one of the oldest trade publications in the U.S.),
stylists frequently address these myths and champion healthier, science-backed
techniques.
Toward Smarter Hair Care
Replace myths with routines based on your hair type: gentle cleansing, minimal heat,
regular trims, and low-tension styling. Over time, hair becomes less brittle, more
resilient, and easier to manage.
